inwiss - integrative enterprise knowledge portal
[an earlier version of this paper has been published as t. priebe and g. pernul: towards integrative enterprise knowledge portals. in proc. of the twelfth international conference on information and knowledge management (cikm 2003), new orleans, la, usa, november 2003.]knowledge portals make an important contribution to enabling enterprise knowledge management by providing users with a consolidated, personalized user interface that allows efficient access to various types of (structured and unstructured) information. todays portal systems allow combining access modules to different information sources side by side on a single portal webpage. however, there is only little interaction between those so called portlets. when a user navigates within one portlet, the others usually remain unchanged, which means that each source has to be searched individually for relevant information. this paper discusses integration aspects within enterprise knowledge portals and presents an approach for communicating the user context (revealing the user s information need) among portlets, utilizing semantic web technologies. for example, the query context of an olap portlet, which provides access to structured data stored in a data warehouse, can be used by a search portlet in order to automatically provide the user with related documents found in the organization s document management system. for this purpose we will present a fuzzy metadata-based search approach. together with the context-based portlet integration this provides for context-supported proactive information retrieval. in particular, the paper shortly presents the inwiss portal prototype that we are building to evaluate our approach, demonstrating such an olap and information retrieval integration. 【程序编程相关:spring 分模块开发简单实践】

a major challenge of todays information systems is to provide the user with the right information at the right time. using web-based technologies, knowledge portals are an emerging approach for providing a single point of access to various types of information, making an important contribution to enabling enterprise knowledge management. this paper discusses integration aspects within enterprise knowledge portals. in particular, the integration of structured information (like olap data stored in a data warehouse) and unstructured information (e.g. in form of documents) is a key issue of this paper. 【扩展信息:Servlet的相关类和接口】
1 introduction
we base our approach on integrated metadata, using a common ontology and ontological concept mapping, together with an approach for context-bases portlet integration. today s portal systems allow combining different portal components side by side on a single portal webpage. however, there is only little interaction between those so called portlets. when a user navigates within one portlet, the others remain unchanged, which means that each source has to be searched individually for relevant information.
this paper presents an approach for global searching and for communicating the user context among portlets. this approach is, to our knowledge, unique. in the concrete case of integrating structured data warehouse data and unstructured documents, the query context of an olap portlet (i.e. the information shown within a certain olap report) can be used by a search portlet to automatically provide the user with related documents found in the organizations document management system. this provides for implicit, proactive information retrieval capabilities.
